6 Electrical Connection
☐ With the exception of the signal generator for the Fast Stop function, all signal generators must always be
designed as make contacts.
Cable requirements for connecting a signal generator:
☐ Conductor cross-section: 1.5 mm² to 2.5 mm² (16 AWG to 14 AWG)
☐ Conductor type: copper wire
☐ Maximum cable length: 30 m (98 ft)
Terminal assignment:
The following table shows the default configuration of the switching inputs and outputs. The functions of the switching
inputs and outputs can be set via the user interface.

Function
Feedback of circuit breaker of genset 1: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
In the redundant system: Switching the respective
other programmable logic controller on and off
Feedback of circuit breaker of genset 2: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
In the redundant system: Changing-over the Redun-
dancy Connector
Feedback of circuit breaker of genset 3: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
In the redundant system: Reading out Feedback 1 of
the Redundancy Connector
Feedback of circuit breaker of genset 4: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
In the redundant system: Reading out Feedback 2 of
the Redundancy Connector
Feedback of circuit breaker of genset 5: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
Feedback of circuit breaker of genset 6: If the con-
tact is closed, the genset is operating and connected
to the local utility grid.
Fast stop
When the signal is used, a fast stop of the inverters
is performed according to the settings on the user in-
terface of the programmable logic controller (see
user manual of the Hybrid Controller).
